Make Obsolete is a weaker but faster Biting Rain that doesn't kill your stuff.

Subtle Strike could kill something, and can pump up one of your finishers if you draw it late. Boon of Emrakul has a similar effect.

Vessel of Malignity discards and gives you more enchantments for delirium.

When Aether Revolt rolls around, Yahenni's Expertise for another board wipe.

Make Obsolete makes sense with token decks. I'll try that.

The only other cards I like are Vessel of Malignity and Yahenni's Expertise. I've played the vessel before and it is very slow so that's out. I'll have to wait for Yanni.

Thanks!

I want Goblin Dark-Dwellers in this deck. It makes Mind Rot so mean. You just spend 2 cards for 4 of theirs plus you get a good creature on board. I understand you aren't going to splash red here so maybe I will buid it...Whispers of Emrakul does not show you their hand. and I concur that Thought-Knot Seer makes a lot of sense, though why not Distended Mindbender? If you're already loving Filigree Familiar so much, I don't see why not.Ideal curve seems like it would go Harsh Scrutiny into Whispers of Emrakul into Filigree Familiar into Distended Mindbender into Goblin Dark-Dwellers into a possible Noxious Gearhulk (which I know doesn't fit with your plan, but it's really useful to have in the deck just in case you get Emrakuled or something somehow).

Cyman,

I like your observations. Whispers of Emrakul was put in as part of my experiment with Creeping Dread but Whispers could be dropped now. Blind discard is not the best.

I prefer Distended Mindbender over Thought-Knot Seer for the same reason I prefer Pick the Brain over Lost Legacy -- I don't want to put cards in my opponent's hand. I used to run Mindbender in an earlier version of the deck and as a 5/5, it would be a good closer. I'll try that creature out again.

Thanks for the comments!

Check out my version... It still needs some help I think. Revolting Shadows of Kaladesh.

Witness the End... :-)
